MAX14431CAEE+

MAX14431CAEE+ is a fast, low-power, 4-channel, digital galvanic isolator. This device transfers digital signals between circuits with different power domains while using as little as 0.58mW per channel at 1Mbps with a 1.8V supply. It offers all three possible unidirectional channel configurations to accommodate any 4-channel design, including SPI, RS-232, RS-485, and digital I/O applications. This device has independent 1.71V to 5.5V supplies on each side of the isolator also makes the device suitable for use as level translators. It is approved by UL according to UL1577, cUL according to CSA bulletin 5A. It is used in applications such as isolated SPI interface, fieldbus communications for industrial automation, isolated RS-485/RS-422, CAN, battery management, and medical systems.
